Calcium Carbonate Masterbatch (CaCO3) for the manufacture of bin bags
Save in bin bag manufacturing processes with the Masterbatch (CaCO3) – PLASPER®
The PLASPER® Calcium Carbonate Masterbatch is a mineral modifier with a high, very fine, treated CaCO3 content that has an excellent dispersion in the final product, indicated for direct addition in the processing of polyolefins. The PLASPER® mineral modifier is designed to increase productivity, reduce energy costs and improve properties.
ADVANTAGES
Economic saving
- Reduction in energy consumption
- Reduction in raw material costs of 3% to 20%, depending on the percentage of PLASPER® used
- Helps reduce thickness
- PLASPER® concentrates produce a whitish appearance on films without pigmentation, which saves the use of TiO2
Improvements in productivity
- The CaCO3 increases the thermal conductivity of the extruded product, which results in faster heating and cooling of the polymer (Fig. 1)
- Improves the processability/transformation and the extrusion performance
- Considerably increases the speed of the line for faster process times
- Facilitates welding
- Improves dispersion
- Improves the impression of the final product
- Better stability of the bubble, increased production and easier transformation
Improves properties
- Improves the anti-blocking effect
- Improves the barrier effect
- Increases the dart drop resistance (Fig. 2)
- Increases resistance to tearing (Fig. 3)
RECOMMENDATIONS FOR USE
- The application of the PLASPER® Masterbatches does not involve any modification to the production process
- The most suitable dosing systems are:
- Gravimetric dosing unit
- Volumetric dosing unit (the best way is to use the feeder at the neck, between the hopper and the extruder)
- Centralised mixing stations also give good results
- Dosing: between 3% and 50%
